RAIL-STAY.

Specification of Letters Patent.

Application filed May 22, 1918. Serial No. 789,238.

anti-creepers, the purpose of which 'is to prevent the longitudinal creep of railwagy rails under the stresses exerted by the passage of trains over the rails.

The primary object of the invention is to provide, in a device of this sort, effective means for preventing aloosening or retro-- 7 grade movement as between the parts which operate to grip or clamp the rail, so as thereby to insure at all times and under all conditions the proper and intended ope-ration of the device. p

The hold of rail stays on the rails becomes loosened from a variety of causes, the chief of which are the vibration to which the rail is subjected by the passage of the train thereover, contraction 'and' expansion of the metal of the rail'andstay due to temperature changes, and the reaction orreverse longitudinal movement which, it is believed, takes place as soon as the train has passed by and the forward stresses cease, Although various expedients have been tried for preventing this tendency of the parts to become loose or back away one from the other, such, for example, as'the use of nut locks on anticreepers of the bolt type and rack and tooth arrangements on devices of the wedge type, none ofthese expedients have proven altogether successful when put to the testof actual service. I

My invention'overcomes this difficulty and solves the problem in a very satisfactory manner by interposing between the rail and some portion of the anti'creeper, or between the relatively movable parts of the anti- -crecper itself, a soft compression and frie 'tion pad or insert of materlal such aswood,

, fiber, vulcanite, soft metal. or the like, which ismore resilient or adhesive, or preferably,

both more resilient and adhesive than the,

metals of which the rail and anti-creeper are composed, which element, besides absorbing vibration, takes a better frictional grip on metal surfaces or surfaces against which it bears than isv possible where thepartsin as applied to several: common types of anti- I forming apart of this rail stay. Fig.-'7,'.is

sert. Fig. 8, is a plan view of another type contact are both relatively-hard metal such as steel or malleable iron. It will beobvious that this expedient might beemployed in a number of different ways upon variously constructed. anti-creepers. I have .shownit creepers. I do not wish, however, to. be understood as limiting the applicability of the of the parts shown in Fig. 1. Fig. 3, isa

view, in perspective, of the key or wedge of the device fitted with a pad of soft material. Fig. 4 is a plan view illustrating another form of rail stay with the'deyice of my invention applied thereto. Fig. 5, is a sectional view taken on line 5-5 of Fig. 4:. Fig. 6, is a view, in perspective, of the wedge across-sectional view of the wedge and. in-

Fig. 9 is a sectional view'taken on line- 9 -9 of Fig. 8. Figs. 10 and 11, are views in per-- spective of the two elements" constituting:

the rail stay shown in Figs. 8' and 9. Fig.

12 is a sectional view of a bolt type of rail stay utilizing the device of my inyention; and Fig. 13, is'a' view in perspective ofone of the jaw elements of this stay; y Like characters of reference designate like parts in the several figures of the drawmg.

Referring first to Figs. 1 to 3, inclusive, A designates a railroad rail and B one of the cross ties-on which it issupported, The rail stay shown for the purpose of illustrating the improvement constituting my invention consists of a malleable iron castin 25 pruvided'at one end with a aw 26 which engages one of the base flanges of the rail, and at the other end, a larger; jaw 27 between which and the-rail is driven a key or wedge 28, the latter being preferably formed with a groove 29 into which the edge of the rail base is received. The casting 25 is formed with a tie-abutting member 30. This part of the device is described and claimed as a, tie-abutting member but it no might of course be arrangedagainst any other fixed element or part- 01- the roadbed, and I do not wish to be understood asexcluding such other arrangements in so describin and claiming this, part. of the device. 11' devices of this type difficulty has always wedge from backing out of its operative position. The constant. vibration ofthe rail operates upon. the wedge to loosen it fromthe jaw into which it is driven; The expension and contgaction of the metal parts due to-'temperature changes may have the same result. faces of the key and of thejaw are both metal and relatively smooth, it does not require a: great deal 'ofvibration to start the wedge backing out ofplao'e, this I fit into the: back edge of the wedge an insert 31 of some relatively soft, comas wood, fiber, soft pressible material such metal, or'the like. This insert, as a matter of convenience in shipping, is fastened to the key in some suitable manner. For example, I have shown-oneend of the groove 32 in which the pad is set undercut as at 33.

A lug 34 on the back of the key atthe other end of the groove is hammered down on the insert so asto hold the same in position.

WVhen the wedge 28 is-driven in. between -the jaw 27 and the base of the rail the-inisert or pad absorbs a good deal of the viis considerably greater than the friction be tween two similarly shaped-surfaces both of bration'to which the device is subjectedan'd .to a certain extent by its resiliency compen- ,36.

sates for looseness due to differences in con'- traction-and expansion between the rail and therail stay and thereby materially de-- creases the forces tending to loos en the the friction between the wedge. Moreover,

insert and the-innersurface of the jaw 27 metal, and this circumstance further checksthe tendency of the wedgeto become, loose. In Figs. 4 to 7, inclusive, the insert is i applied to thesame typeof rail stay in a 35 corresponding to the i whichis fitted a wood or the like, one edge 37 of which bears against the inner surface ofthe jaw '27,.the

flange of the rail. N mizes slip both betweenthe \wedge andfthe .othcr casting of the stay and between the 2.6 I an'insert 36 of wood, or. the like, ma e;

somewhat different manner from thatshown in the preceding figures.

comprising elements one of which ismovable and the-- rail said wedge with the otherunder the base of the rail, the casting 39 being formed with a tapered groove 41 and the casting 40 with a tongue 42 which slides in this groove. One of the castings, for example the casting 39, is provided with a tie-abutting member 43. The hold of the device on the rail depends.en-' tirely upon the frictional grip which the jaw members 39 and 40 take, upon the base of the rail. This frictional grip isvery' ma- 7 'terially increased and the danger .of the same being loosened ,by vibration. di-V minished by providing one or each of the castings with a compressible, relatively ad- In the drawings I have shown the casting 39 provided with an insert 44 of this character and the cast ing 40 with a similar insert 45. As shown, these'inserts are "arranged under the base flange of the rail. I

In Fig. 12 I have shown the same ex-v pedient as employed in connection with the bolt type of rail stay. The device is'made up of two 'jaw members 46, 4-7 held together by a bolt 48 and nut 49. Either of said sive material to increase bration, or, if need be, both jaw members may be so constructed. I have shown each Jaw member furnished with asoft, .com-
